"Although its collapse has dominated recent media coverage, the financial sector is not the only segment of the U.S. economy running into serious trouble. The institutions that govern the labor market have also failed, producing the unusual and
unhealthy situation in which hourly compensation for American workers has stagnated even as their productivity soared. Indeed, from 2000 to 2007, the income of the median working-age household fell by $2,000 – an unprecedented decline. In that time, virtually all of the nation’s economic growth went to a small number of wealthy Americans. An important reason for the shift from broadly-shared prosperity to growing inequality is the erosion of workers’ ability to form unions and bargain collectively.
A natural response of workers unable to improve their economic situation is to form unions to negotiate a fair share of the economy, and that desire is borne out by recent surveys. Millions of American workers – more than half of non-managers – have
